Abstract (en)
[origin: WO9312761A1] The present invention relates to solid complex particles each comprised of at least two solid substances, at least one of them being biologically active. The biologically active solid substance is comprised of at least one biologically active product and is evenly distributed at the surface of a grain consisting of the other solid core-forming substance, so-called support substance, said grain having a size comprised between 0.05 and 100 $g(m)m (microns) and the weight ratio between said active substance and said core-forming substance being comprised between 10?-4 and 1.5 approximately. The invention also relates to a method for the preparation of said particles, a process for the treatment of a biological surface in order to accelerate the biodisponibility of a biologically active substance. It also relates to compositions for topical application containing the particles of the invention.
Abstract (fr)
La présente invention concerne des particules solides complexes composées chacune d'au moins deux substances solides dont l'une au moins est biologiquement active. La substance solide biologiquement active est composée d'au moins un produit biologiquement actif et est régulièrement répartie à la surface d'un grain constitué de l'autre substance solide formant coeur, dite substance support, ledit grain ayant une dimension comprise entre 0,05 et 100 mum (microns) et le rapport pondéral entre ladite substance active et ladite substance formant coeur est compris entre environ 10-4 et 1,5. L'invention concerne également un procédé de préparation de ces particules, un procédé de traitement d'une surface biologique pour accélérer la biodisponibilité d'une substance biologiquement active. Elle concerne également des compositions à usage topique contenant les particules de l'invention.
